Question

The postive and negative coterminal angle for 11pie/6

Answer 1

The positive coterminal angle is obtained by adding 2π to the given angle, as follows:

`(11\pi)/(6)+2\pi=((11)/(6)+2)\pi=(11+2\cdot6)/(6)\pi=(23)/(6)\pi`

The negative coterminal angle is obtained by subtracting 2π to the given angle, as follows

`(11\pi)/(6)-2\pi=((11)/(6)-2)\pi=(11-2\cdot6)/(6)\pi=-(1)/(6)\pi`
